Rockville sent a isolation shield without hardware to set it up. I called and talked to LuLu and told her the parts were Missing. She sent me a return mailing via email. She told me that they would make sure all the parts would be sent after they received the isolation shield back. After waiting over a week I received the new one. Low and behold more parts were missing. I emailed them again and they had the nerve to tell me to take photos of the missing parts that they didn't send me. Someone in shipping should be fired.
